Description
Incus is a system container and virtual machine manager. Prior to version 7.2.0, an arbitrary file write exists in the Incus client when a malicious image server returns a crafted `Incus-Image-Hash` header. This can lead to arbitrary command execution as root on the server. Version 7.2.0 patches the issue.
